What is Sierra?

Sierra is an AI platform that enables businesses to build, deploy, and optimize conversational AI agents for customer experience. Founded by Bret Taylor and Clay Bavor, Sierra helps companies like WeightWatchers, SiriusXM, and ADT create personalized, multichannel customer interactions. The platform addresses the problem of scaling high-quality customer service by allowing teams to build AI agents without extensive engineering support. Core capabilities include a no-code agent builder called Ghostwriter, an Agent Data Platform for personalization, and tools for optimization and observability. Sierra supports deployment across chat, SMS, WhatsApp, email, voice, and ChatGPT. It is designed for customer experience leaders, product managers, and support teams looking to increase customer lifetime value. The platform emphasizes outcome-based pricing, ensuring customers pay only for the value delivered. Sierra fits into workflows that require rapid agent creation, continuous improvement through experiments, and deep integration with existing customer data.
